It sounds like a caching issue - proxy servers do weird things with caching.
I would try using the headers with different values to see if it makes any
effect:
response.setHeader("Cache-Control","no-cache");
response.setDateHeader ("Expires", 0);
Those lines should prevent caching at the proxy server.

Subject: Proxy & Disappearing Parameter
Dear Friends,
I am experiencing a really funny problem.
We have a JSP Application running on JRun 3.1. This is a Local Intranet
Application.
I have a hidden field in form
<input type="hidden" name="mode" value="0">
When I submit the form I get following strage results.
Situation 1. Bypass the Proxy Server
First time I get the value of mode.
If I use back button of browser and submit again the parameter
becomes null.
Situation 2. Go thru proxy server
I always gets the value irrespective of first time or second time.
Since going thru proxy slows down the access we do not want to use
that.
Could anyone throw some light to this strage problem.
Thanks in Advance...
Savant
